[ SCORE SCALE ]

The Public Verdict Has A Range.

The level explains the estimated context. It is not a certification.

0.80-1.00

Strong clarity

The pictogram communicates well in this context.

Use it, then keep testing with real users.

0.65-0.79

Usable with support

The pictogram works with labels or context.

Pair it with text and monitor interpretation.

0.50-0.64

Current report

The pictogram carries meaningful clarity risk.

Improve the symbol before relying on it.

0.00-0.49

Not reliable

The pictogram does not communicate enough alone.

Replace it or add strong alternative support.

[ CONVERGENCE PROFILE ]

Where Meaning Converges.

The profile compares visual evidence, semantic extraction, cultural recognition, time, and cognitive context. It describes estimated convergence, not universal validity.

Evidence Notes.

8 Findings Published

Evidence

Primary referent: high chair.

Evidence

Implied function: The icon must communicate High Chair in a digital interface..

Evidence

Metaphor type: functional.

Evidence

The icon effectively represents a high chair with a strong primary referent and functional meaning aligned to its intended use in digital interfaces.

Evidence

Visual metrics indicate good perceptual robustness with strong scores in visual complexity, cohesion, and resilience to size and blur effects, supporting recognition at small sizes.

Evidence

Semantic and functional convergence scores are moderate, reflecting some ambiguity potential especially with similar furniture icons like bar stools or child chairs.

Evidence

Cultural convergence is relatively low, indicating limited widespread cultural recognition and evidence supporting shared understanding of the symbol.

Evidence

Temporal and neurocognitive convergence scores suggest the icon maintains meaning over time and aligns moderately well with pictogram reading principles, but requires some learned convention.
